Historically, the access point functionality in FreeBSD has suffered
from serious compatibility or performance problems with some wireless
clients. Over time this has improved significantly. pfSense access
points are used in various locations with no trouble. It is used with
various clients such as MacBook Pro, Apple AirTunes, Mac mini, iPod
Touch, Adroid devices, Palm, various Windows laptops, Xbox 360, and
FreeBSD clients and it works very reliably.

There is the possibility of finding incompatible devices with any access
point. FreeBSD is no exception and it can be more common with FreeBSD
than other access points. Using pfSense as an access point can work
quite well with the right card and configuration.

In general, we still recommend Using Existing Wireless Routers with pfSense, especially if
802.11n or 802.11ac are required. Placing that burden on an external
device and allowing pfSense to focus on the firewall/routing/NAT/etc can
be simpler in the long run. An access point may still be connected to a
dedicated interface or VLAN for isolation purposes.
